Hoverboard. Sure, the DeLorean in the Back to the Future movies was a cool time traveler,

與馬蒂不同的是，薩帕塔很聰明，戴了一個頭盔。
Bluetooth. In his futuristic 1953 novel Fahrenheit 451, Ray Bradbury anticipated Bluetooth,

At $100, this baby cost a lot of bread, which maybe why it was discontinued just two years after launch.

Wifi. Nikola Tesla called it! In 1909, the famed electrical engineer told the New York Times,

“在全世界范圍內，我不久將有可能實現簡單地傳送無線信息，任何人都可以攜帶和操作自己的設備?！?/div>
No doubt he was thinking of the Kérastase Hair Coach brush, which measured brushing speed and employed a microphone to listen to your hair,

all to compute an overall hair-quality score sent to your smartphone. (Alas, it too is gone.)
所有這些都是為了計算發送到智能手機的整體頭發質量評分。(唉，它也消失了。)
GPS. Writer Arthur C. Clarke (2001: A Space Odyssey) saw a world in which no one got lost.
全球定位系統。作家亞瑟·C·克拉克(2001：太空漫游)預測到了一個沒有人迷路的世界。

1956年，他寫道，衛星“可能使定位網格成為可能”，這樣，任何人都可以通過手表大小的儀器上的兩個刻度盤來確定自己的位置。”

克拉克沒有提到他的系統可以跟蹤另外一個人，比如一個罪犯。
